Question
A solutions architect has an operational workload deployed on Amazon EC2 instances in an Auto Scaling group. The VPC architecture spans two Availability Zones (AZ) with a subnet in each that the Auto Scaling group is targeting. The VPC is connected to an on-premises environment and connectivity cannot be interrupted. The maximum size ol the Auto Scaling group is 20 instances in service. The VPC IPv4 addressing is as follows:
VPC CIDR: 10.0.0.0/23 AZ1 subnet CIDR: 10.0.0.0/24 AZ2 subnet CIDR: 10.0.1.0/24 Since deployment, a third AZ has become available in the Region. The solutions architect wants to adopt the new AZ without adding additional IPv4 address space and without service downtime. Which solution will meet these requirements?
Options
- AUpdate the Auto Scaling group to use the AZ2 subnet only. Delete and re-create the AZ1 subnet
- BTerminate the EC2 instances in the AZ1 subnet. Delete and re-create the AZ1 subnet using half
- CCreate a new VPC with the same IPv4 address space and define three subnets, with one for each
- DUpdate the Auto Scaling group to use the AZ2 subnet only. Update the AZ1 subnet to have half
